One side of the multiple guide cylinders 608 is fixedly connected to a return spring 609. One side of the return spring 609 is fixedly connected to one side of the lifting adjustment plate 607, and one side of the hollow annular flow-reducing frame 610 is fixedly connected to one side of the guide cylinder 608.

[0022] In the present invention, the precision carving stabilization module 6 further includes: Two metal regulating nozzles 603 are symmetrically fixedly connected to the lower sides of the fine carving control box 602 through a mounting base. The metal regulating nozzles 603 are used to spray cutting fluid on the fine carving knife body 604 and the cutting opening; Two tooling blocks 614 are fixedly connected to one side of the hollow annular slow-flow frame 610. One side of each tooling block 614 is movably connected to a reciprocating push rod 615. Both sides of the lifting adjustment plate 607 are connected to a rotating shaft 617 through a bearing. The rotating shaft 617 on the same side and the reciprocating push rod 615 are movably connected to the same electric drive rod 618. Two spoilers 616 are fixedly connected to one side of the reciprocating push rod 615 , and the spoilers 616 are located inside the hollow annular flow-delaying frame 610 .

[0023] In the present invention, the precision carving stabilization module 6 further includes: The tooling support plate 605 is fixedly connected to one side of the precision carving control box 602. A liquid collecting frame 606 is fixedly connected to one side of the tooling support plate 605. The liquid collecting frame 606 is used to recycle the used cutting fluid; Two rotating circular tubes 625 are connected to both sides of the liquid collecting frame 606 through bearings. The opposite side of the two rotating circular tubes 625 is fixedly connected to the same filter cartridge 626. The filter cartridge 626 is located inside the liquid collecting frame 606. A liquid outlet groove 611 is equidistantly provided on the side of the hollow annular slow flow frame 610 facing the frame 1.

[0024] In the present invention, the precision carving stabilization module 6 further includes: A circulation pump 622 is fixedly connected to one side of the tooling support plate 605. The liquid inlet end of the circulation pump 622 is movably connected to the interior of one of the rotating circular tubes 625 through a liquid inlet pipe 623. The liquid outlet end of the circulation pump 622 is fixedly connected to a liquid outlet pipe 621. The hollow liquid collecting box 619 is fixedly connected to one side of the tooling support plate 605. Two outlet holes are opened on one side of the hollow liquid collecting box 619. The inside of the two outlet holes is fixedly connected to a metal telescopic tube 620. One end of the metal telescopic tube 620 is fixedly connected to the inside of the hollow annular flow-slowing frame 610. One side of the liquid collecting frame 606 is fixedly connected to a U-shaped support rod 624.

[0025] In a specific application scenario, the fine carving knife body 604 is moved to the top of the mobile phone cover through the steering mechanism 601 and the fine carving control box 602 to realize the fine carving operation. During the fine carving process, the cutting fluid is sprayed on the fine carving knife body 604 by aiming the metal adjustment nozzle 603 at the fine carving knife body 604. The cutting fluid is blocked by the space generated by the hollow annular slow flow frame 610 and the mobile phone cover, so that the cutting fluid slowly flows out through the liquid outlet 611 opened by the hollow annular slow flow frame 610. At the same time, the electric drive rod 618 is started, and the reciprocating push rod 615 is driven by the electric drive rod 618 to make the spoiler 616 intercept the cutting fluid for a second time, thereby further reducing the flow rate of the cutting fluid. The cutting fluid flowing out of the groove 611 falls into the liquid collecting frame 606, is filtered by the filter cylinder 626 inside the liquid collecting frame 606, and then is transported to the inside of the hollow liquid collecting box 619 through the circulation pump 622, and is transported to the inside of the hollow annular slow flow frame 610 through the metal telescopic tube 620. Cutting fluid is continuously added to the space between the hollow annular slow flow frame 610 and the mobile phone cover. Through the fine carving stabilization module 6, when the cutting fluid is sprayed on the fine carving knife during the fine carving of the mobile phone cover, the flow rate of the cutting fluid is reduced, so that the cutting fluid can effectively reduce the vibration and noise generated during the cutting process, thereby improving the stability of the fine carving machine processing.

[0026] It should be noted that the hollow annular flow-relief frame 610 surrounds the outside of the fine carving knife body 604. At the same time, when the fine carving knife body 604 is finely carving the mobile phone cover, the ball 612 below the hollow annular flow-relief frame 610 is against one side of the collection cover. The hollow annular flow-relief frame 610 is adaptively adjusted on the lifting adjustment plate 607 through the guide cylinder 608 and the return spring 609. During the movement of the fine carving knife body 604, the hollow annular flow-relief frame 610 moves above the mobile phone cover through the ball 612. The contact area between the ball 612 and the mobile phone cover is small, which reduces the friction on the mobile phone cover.

[0027] Reference Figure 1 、 Figure 2 、 Figure 7 and Figure 8 In a preferred embodiment, the anti-blocking collection module 7 includes: Two hollow air-blowing rods 702 are connected to both sides of the liquid collecting frame 606 through bearings. Air-blowing ports are evenly spaced on both sides of the two hollow air-blowing rods 702. Air-blowing nozzles 703 are fixedly connected to the interior of the multiple air-blowing ports. The magnetic plate 701 is fixedly connected to one side of the liquid collecting frame 606 and is used to collect metal dust inside the collected cutting fluid; There are multiple cleaning brush plates 705 , one side of the cleaning brush plates 705 is fixedly connected with an extrusion spring 704 at equal distances, one side of the extrusion spring 704 is fixedly connected to one side of the hollow air rod 702 , and the cleaning brush plates 705 clean the outside of the filter cartridge 626 .

[0028] In the present invention, the anti-blocking collection module 7 further includes: The linkage gear 709 is fixedly connected to the outside of one of the rotating circular tubes 625. A bidirectional motor 711 is fixedly connected to the outside of the liquid collecting frame 606. The driving end of the bidirectional motor 711 is fixedly connected to a rotating gear 712. The rotating gear 712 meshes with the linkage gear 709. The air pressure pump 706 is fixedly connected to the outside of the liquid collecting frame 606. The air pressure end of the air pressure pump 706 is movably connected to the inside of the hollow air rod 702 through the air pipe 707. The driving end of the bidirectional motor 711 is fixedly connected to the outside of the two hollow air rods 702 with pulleys. The external transmission of multiple pulleys is connected by the same belt 710. Two L-shaped support rods 708 are fixedly connected to the outside of the liquid collecting frame 606 .

[0029] In a specific application scenario, when the filter cartridge 626 filters the used cutting fluid, the bidirectional motor 711 is started, and the bidirectional motor 711 drives the rotating gear 712 to make the linkage gear 709 rotate in both directions, so that the filter cartridge 626 and the hollow air-blowing rod 702 rotate in both directions at the same time. The elasticity of the extrusion spring 704 makes the cleaning brush plate 705 fit tightly to the outside of the filter cartridge 626, so as to clean the outside of the filter cartridge 626. At the same time, the air pressure pump 706 is started, and the air nozzle 703 on the hollow air-blowing rod 702 is used to blow air to the outside of the filter cartridge 626, so that the metal dust in the cutting fluid falls off from the outside of the filter cartridge 626 to avoid blockage of the filter cartridge 626. At the same time, the magnetic plate 701 at the bottom of the liquid collecting frame 606 absorbs the metal dust to avoid secondary adhesion to the outside of the filter cartridge 626.

[0030] It should be noted that the magnetic plate 701 is located at the bottom of the liquid collecting frame 606. When there is a lot of metal dust on the magnetic plate 701, the magnetic plate 701 is turned on to collect the metal dust.

[0031] Reference Figure 1 、 Figure 2 、 Figure 9 and Figure 10 In a preferred embodiment, the carving auxiliary module 8 includes: A servo motor 803 is disposed inside the frame 1. The driving end of the servo motor 803 is fixedly connected to an intermittent rotating rod 801. One end of the intermittent rotating rod 801 is fixedly connected to a load-bearing mold 802. Slide grooves are provided at equal intervals on one side of the load-bearing mold. Two limiting cylinders 804 are fixedly connected to opposite sides of the multiple slide grooves.

One side of the multiple sliders 806 is fixedly connected to an adjustment handle 808.

[0032] In a specific application scenario, when fine-carving a mobile phone cover, the mobile phone cover is placed on the supporting mold 802, and at the same time, the adjustment handle 808 is pulled to make the slider 806 drive the rubber clamping plate 807 to move to one side, and the reset spring 2 805 is squeezed. After the placement is completed, the reset spring 2 805 is reset to position the rubber clamping plate 807 to the mobile phone cover, thereby avoiding displacement when the mobile phone cover is fine-carved.

[0033] It should be noted that the supporting mold 802 is rotated intermittently by the intermittent rotating rod 801 on the servo motor 803, which avoids the workers from taking and placing the mobile phone cover under the fine carving knife body 604. The fine carving auxiliary module 8 cooperates with the steering mechanism 601 to rotate to realize the flow processing operation of the device on the mobile phone cover.

[0034] Reference Figure 1 and Figure 2 In a preferred embodiment, two collecting troughs 9 are provided inside the frame 1, and mounting openings are provided at equal distances on one side of the frame 1, and one side of each of the mounting openings is connected to an opening and closing cover plate 5 via a hinge.

[0035] A method for using a precision engraving device for producing mobile phone cover plates, using the precision engraving device for producing mobile phone cover plates as described above, comprising the following steps: Step 1: When fine-carving the mobile phone cover, the mobile phone cover is placed on the supporting mold 802, and the adjustment handle 808 is pulled at the same time, so that the slider 806 drives the rubber clamping plate 807 to move to one side, and the return spring 805 is squeezed. After the placement is completed, the return spring 805 is reset to position the rubber clamping plate 807 to the mobile phone cover, and then the fine-carving knife body 604 is moved to the top of the mobile phone cover through the steering mechanism 601 and the fine-carving control box 602 to realize the fine-carving operation; Step 2: During the fine carving process, the cutting fluid is sprayed by aligning the metal regulating nozzle 603 with the fine carving knife body 604. The cutting fluid is blocked by the space formed by the hollow annular slow flow frame 610 and the mobile phone cover, so that the cutting fluid slowly flows out through the liquid outlet 611 opened by the hollow annular slow flow frame 610. At the same time, the electric drive rod 618 is started, and the reciprocating push rod 615 is driven by the electric drive rod 618 to make the spoiler 616 intercept the cutting fluid for a second time, thereby further reducing the flow speed of the cutting fluid. Step 3: The cutting fluid flowing out of the liquid outlet 611 falls into the liquid collecting frame 606, is filtered by the filter cartridge 626 inside the liquid collecting frame 606, and then is transported to the hollow liquid collecting box 619 by the circulation pump 622. The cutting fluid is then transported to the hollow annular slow flow frame 610 through the metal telescopic tube 620, and the cutting fluid is continuously added to the space between the hollow annular slow flow frame 610 and the mobile phone cover. Step 4. When the filter cartridge 626 filters the used cutting fluid, the bidirectional motor 711 is started, and the bidirectional motor 711 drives the rotating gear 712 to make the linkage gear 709 rotate in both directions, so that the filter cartridge 626 and the hollow air-blowing rod 702 rotate in both directions at the same time. The elasticity of the extrusion spring 704 makes the cleaning brush plate 705 fit tightly to the outside of the filter cartridge 626, so as to clean the outside of the filter cartridge 626. At the same time, the air pressure pump 706 is started, and the air nozzle 703 on the hollow air-blowing rod 702 is used to blow air to the outside of the filter cartridge 626, so that the metal dust in the cutting fluid falls off from the outside of the filter cartridge 626 to avoid clogging of the filter cartridge 626. At the same time, the magnetic plate 701 at the bottom of the liquid collecting frame 606 absorbs the metal dust to avoid secondary adhesion to the outside of the filter cartridge 626.
